AURORA — Aurora police are reviewing policies and procedures used in an officer-involved shooting that left a man dead last weekend.

On July 23, Juan Contreras was shot and killed by an Aurora police officer in the 12100 block of East Colfax Avenue during an extortion investigation.

A Tactical Review Board announced Friday that it will look into whether any of the officers involved violated department policies, training and decisionmaking procedures.

The Arapahoe County District Attorney’s Office will ultimately determine whether criminal charges should be filed. An internal-affairs investigation also will be conducted.

“Could we have done this better?” Police Chief Dan Oates said in a statement. “We have an obligation to be the best we can be as a police department, and if we can learn from what occurred here and thereby avoid a deadly confrontation in the future, that will be a positive outcome.”

It was the fifth fatal shooting by Aurora officers this year. Officers were cleared by district attorneys in the previous four cases.

Contreras, 59, was shot three times by an Aurora officer, who was punched multiple times through an open car window, according to police spokesman Bob Friel.

Earlier that Saturday, an elderly woman called police to say someone had left a note on her car demanding $50 for her keys, which she had earlier lost.

The officer, who was in plainclothes and did not have his badge, used the woman’s spare keys and drove her car to a Family Dollar parking lot to meet Contreras.

As the officer met Con treras at the parking lot, he told the officer the price for the keys was now $100.

The officer then tried to arrest Contreras, but he punched the officer several times and tried to reach for a knife from the center console of his car. That’s when Contreras was shot and killed.

Witnesses said the officer identified himself as a police officer several times.

The sergeant and lieutenant working on the case approved of the undercover operation.

“This event has triggered a number of questions both within the department and the community,” Oates said. “We need to take a thorough look at the decisions we made that evening and the tactics we employed.”
